Yes, it is possible, but that does not mean it is easy.
From the ServiceNow documentation:
"If you are interested in integrating ServiceNow with your intranet you should be aware that the ServiceNow login portlet is the only content supported within an iframe HTML element. Any other method of attempting to include the ServiceNow platform outside of your instance is not supported.
There are several ways you can add a ServiceNow login link to your intranet.
You can add a login link by:
- Enabling the PortletLogin Script include to be Client Callable.
- Creating a simple HTML link to your instance that takes your users directly to the ServiceNow login page.
- Adding an iframe link to the ServiceNow login portlet in one of your HTML pages to permit direct login."

You will also need to set a System Property to enable your portal to render outside of ServiceNow. You will need to set it to false.
| glide.set_x_frame_options | Enable this property to set the X-Frame-Options response header to SAMEORIGIN for all UI pages. The X-Frame-Options HTTP response header can be used to indicate whether or not a browser should be allowed to render a page in a <frame> or <iframe>. Sites can use this to avoid clickjacking attacks, by ensuring that their content is not embedded into other sites. https://developer.mozilla.org/en/the_x-frame-options_response_header Default: Yes |
